The rotation must then take place counter to the third biasing force of the weight balancing device and thus with greater force. This can be detected by the load monitoring device 78 and is used to switch off the door drive 14. In addition, the second traction means Z2 is then loosened, so that the second blocking device 160 engages and a Procedure of the door leaf 14 is blocked in any direction. As a result, the remaining traction means Z2 is relieved, without the risk of a crash of the door leaf 18 exists.
  • the controller 70 can thus determine on which side S1, S2 a voltage drop has occurred and can issue a corresponding error message, for example as plain text.
  • the second latch 168 need not - as in Fig. 1 shown - extend over the entire region of the vertical guide 16b. It is sufficient if only a lower area is provided with the second latching device 168. Then falls the second traction means Z2 in the in Fig. 2 shown closed position - which represents the most common operating state of the gate - from, then immediately the second blocking device 160 is blocked, and the gate 10 can not be opened.
  • this is the second locking device seen from below only provided with about 3 to 10 second locking elements, which are detected by the sear 323. It could thus be that above the in Fig. 10 shown Area of the guide 16 no locking elements of the second locking device 168 are more available.
  • a further first latching device 158 is provided with corresponding latching elements for preventing a fall of the door leaf 18 in the closing direction R2.
  • the second sear 323 is either designed so that it can be supported against the first latching device 158 against movement in the closing direction R2 and can be supported against the first latching device 168 against movement in the opening direction R1.
  • the second blocking element 164 is formed with two catch pawls, namely once with a first catch 223 and secondly a second catch 323, both of which are triggered upon breakage of the second pulling means Z2.
